“…The studies on flexion or extension of the wrist show large differences in exposure levels that are already associated with an increased occurrence of CTS, as was found for three case-control studies. Nordstrom et al (52) presented an increased risk of CTS with bending the wrist for >3 hours/day, Blanc et al (58) reported hand bending >2 hours/day as a risk factor, whereas, in the study of De Krom et al (43), the risk was already elevated when the wrist was extended or flexed for 1 hour/ week. These results, all based on self-reported exposure, are too contradictory for drawing any meaningful conclusion about harmful exposure levels.…”

“…Three articles reported a significant association between exposure to vibration and CTS, with OR values of 2.52 to 4.8 (46,51,52). An increased risk of CTS was found for workers using vibrating tools (1-20 years and >20 years) and power tools or machinery (6-11 hours/day) (46,52). In the cross-sectional study of Bovenzi et al (51), 8-hour time-weighted exposures of 4.7 m/s 2 and 3.9 m/s 2 to hand-arm vibration were associated with CTS.…”

“…Six articles presented significant associations between postural load and CTS (20,29,43,52,57,58). Significant associations were found for activities with a flexed wrist for 1-7, 8-19 and 20-40 hours/week, activities with an extended wrist for 1-7, 8-19 and 20-40 hours/week, and bending hands or wrists for 3.5-6 and 7-16 hours/day, the OR values ranging from 1.3 to 8.7 (43, 52 ,58).…”

“…Carpal tunnel syndrome is commonly seen with occupations that require repetitive tasks involving the hand and wrist, including mouse use, keyboarding, painting, and jobs with similar duties. Although repetitive stress has been well documented as the mechanism of injury for CTS, 27,28 other factors may predispose a patient to injury. These factors include a squarer anatomical configuration of the wrist and carpal tunnel, 29 and wrist angles maintained at greater than 20°of extension while typing.…”

Objective: Work-related upper limb disorder (WRULD) encompasses a broad array of occupational upper limb injuries, the most common being carpal tunnel syndrome (CTS). Carpal tunnel syndrome occasionally presents with concomitant ganglion cysts. The purpose of this case report is to describe the chiropractic management of a patient with bilateral WRULD complicated by ganglion cysts. Clinical Features: The patient was diagnosed previously with bilateral CTS and presented with common CTS symptoms that were nonresponsive to several previous courses of care. Magnetic resonance imaging revealed bilateral ganglion cysts, and electrodiagnostic studies found left CTS and bilateral radial neuralgia. Right limb findings appeared more consistent with nonspecific arm pain. Intervention and Outcome: Chiropractic manipulative therapy, soft-tissue approaches, and physiotherapy modalities were applied to the arms and wrists over a 3-month period. Home care included exercises using elastic tubing and a gyroscopic handheld device. Chiropractic manipulative therapy and other conservative approaches resulted in subjective improvements of decreased hand paresthesias and muscle weakness and objective improvements in range of motion and neurologic deficits. Although the patient's symptoms and function improved, she remained with a level of permanent impairment. Conclusion: This case demonstrates successful chiropractic management of a patient with WRULD complicated by ganglion cysts. Further larger-scale studies are recommended to determine if chiropractic management demonstrates positive outcomes for this condition.

“…Nordstrom et al [37] found the risk of CTS increased 8% for each unit of increase in BMI (about 6 lbs.). Nathan and Keniston summarized that being overweight, older, and physically inactive are major risk factors for slowing (of the median nerve) and clinical CTS [33].…”

Introduction Carpal tunnel syndrome (CTS) is thought to be due to compression of the median nerve in the carpal tunnel. It is known that carpal tunnel pressures are elevated in wrist postures of flexion and extension and in those patients with CTS. Classic symptoms of CTS include night waking with pain, tingling, and numbness. These classic symptoms stimulated our interest in the relationship of sleep to the development of CTS. Method We reviewed the literature surrounding the epidemiology of CTS and the literature regarding sleep disturbances. Through careful distillation of these studies and a process of reasoning, we have developed a hypothesis for a causal mechanism of CTS.Results Epidemiologically, it has been shown that CTS is associated with age, gender, increased body mass index (BMI), diabetes, pregnancy, and is more common in some populations. The same associations noted above for CTS are strongly associated with sleep disturbances. Sleep disturbances due to age, gender, BMI, pregnancy, and population variations are all associated with sleeping in the lateral position supporting the hypothesis that a common causative mechanism of CTS is sleeping in a lateral position. Discussion We believe that the epidemiologic associations with CTS act through a common causative mechanism, increased sleeping in the lateral position which puts the wrist at increased risk of flexion or extension, compressing the median nerve in the carpal tunnel. This hypothesis is simple and explains the connection between a previously unconnected group of epidemiologic associations. This realization has real clinical significance in that it focuses our attention on the early disorder when it is completely reversible. It clarifies previously confused clinical circumstances, creates research questions that can be tested, and it invites us to change our clinical perspective in this most common form of nerve compression.
